Composition of particles emitted at largep T and medium angles inpp, dd, andαα collisions at the CERN intersecting storage rings

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The relative yields of kaons and protons compared with the yield of pions at highp T and polar angles θ away from 90° (in the range from 10° to 45°) are presented forpp, dd, and αα interactions at a centre-of-mass energy\(\sqrt {s_{NN} } = 31\) GeV per nucleon-nucleon collision. The measured particle ratios depend on the atomic mass numberA of the beam particles and on θ. TheA dependence of the ratios becomes stronger for largerp T and is more pronounced at smaller polar angles.
